There is a 3rd party install that allows you to add the same features. I looked at it a few months back but did not buy it. I forgot the name of the company so I can't help you but it is out there. Apple wants to pimp their new products to get you on board to upgrading to new stuff every year. I spent $800 on my 64 gig iPad1 and still love it and use it everyday. I see my next upgrade to a new iPad when they make useful additions. They could have put a camera on version 1 but waited to add an extra selling point.
I have an iphone 4 and I am looking forward to the iphone 6, yes I said 6.
